Application filed august 16, 18%.

This invention rehlitcs to surgical equipment for ear, nose and throat treatmentand operations, and more particularly to an electric'al equipped surgical apparatus having]; an air pump portion demountably arranged thereon for use as a complete independent unit.

Another object of the invention is the pro vision of an apparatus of the character de scribed havinp; a table and an electrically driven air pump unit supported thereon and controlled therefrom, said unit being: compactly constructed and demountable from said table to serve as a complete independent unit, the table and said unit having co-oper atiup; elements whereby positioniiur of the unit on the table disposes the unit in cooperative relation to the apparatus.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

lVith the above exception, the invention ac cordingly consists in the featin'es of constructiou, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indi cated in the following claims.

In the accompanying; drawing, in which is shown one of the various possible illustrative embodiments of this invention,

Referring in. detail to the drawinu, the sur- ,eical apparatus shown in F' 1 includes a table 10 constructed prefcu'abl' ,r of metal. Said table may have sl'iaped angle iron ll mormted on rubber tired casters 153, a top.

1.3, drawers let beneath the top for storing in.- struments and sundries, and a sl'ielf 15.

A. box 16 of rectangular cros section may be secured to the table 10 with its upper Elerial Ne. 23%,428.

side 16 zuljaceut the top 13. The side l6 :uupports a motor control switch 17, gages and control valves 19, the purposls of wh ch. will. herenafter be referred to, and various operating accessories not shown.

an air pump 520 having; the parts thereof compactly mounted on a baseboard 91. is supported on the shelf of the table 10. Said air pump 20 is adapted to be easily and ouielrly dismounted from the table ill) as a unit by means of a suitable handle 22 to permit convenient transportation thereof. As seen from i 2, the air pump has a motor Elli which controlled by a rotary switch 24, and. a resistance coil or rhcostat 25, the latter l'leinp utilized t'm' preheating the air. llfotor 52:3 drives a friction disc 26 which operatesa pres re air pump 27 throughconnecting: rod 28, air being delivered at outlet 29 of a puris tier 30. The motor driven pumping apparatus above described may be similar tothat disclosed in Patent No. 1,469,608 granted to Leopold Steiner October 2, 1923. i

A preferred form of preheater construction irihown in Fig 5 and comprises a hollow cylindrical res ance coil which surrounds a tube 36 through which the air is passed. The inlet side 36 of the tube 36 is normally crmnected by a flexible tubing 37 to the outlet 29 of the purifier 30, audthe outlet side 36" of said tube 36 may be connected to supply heated air wherever needed, as for example to an other bottle (not shown).

it suction pump 31 um also be driven from the said disc 26, the air being; first passed througrh purifier 32. The pumps E27 and 31 and pruritiers and 32 are practically identical with the exception that pump is connected to deliver air under pressure, and plump ii to simultaneouslv produce a suctien at inlet 63 of the purifier 32.

h. 3. air pump 520 is mounted on the shelf 15, it is preferably connected to a pip. o system, not shown, which incorporated in the frant c wort: of the table 10, said system termiiuatingr with the male coupling member El for the air presr-iure side and member or bill? suction side on front legs ll of the .l table ll) as shown in liip; l.

A. dominant hiurture of this in veutio'u resides in the construction whereby the air pump 520 may be used and electrically controlled as a complete imhmemleut unit dis mounted from the table 10 as shown in Fig. 2 or in combination with the table 10 as shown in Fig. 1- aswill hereinafter more fully appear.v

When pump 20 is being used as an independent unit, power to run the motor 23 is supplied through a plug connection 38 this case since the motor is small and the apparatus may thus be quickly and simply brought into operation, in the shortest possible time.v Thethird point, marked Low connects in circuit the entire-resistance 25 and the fourth,.fifth, and sixth points successively cutout portions of the, resistance in the well known. manner. The seventh and last point, marked High cuts out the last portion of the resistance, and the motor then operatesdirectlyacross the power line as it does on the second switch point.

From the description given above, it is clear-that the air pump 20, as an independent complete unit may be' conveniently transportedand put'in operation in various places to, suit-different requirements, asfor instance, it may be removed from the table 10 in'the surgeonsoffice and carried to a patients home and put in service there or may bemade conveniently available. for other like; purposes.

The air pump 20 when used in combination with a-table, 10 is mounted on shelf 15. This arrangementwhich is compact and neat permits easy interconnection of the air pump 20 with the piping system and control incorporated in the table structure, not fully shown but described inmy aforementioned co-pending application for various surgical treatments and operations. As shown in Fig. l, the control of the combined apparatus is most convenientlyarranged on side 16 of box 16 where the'switch 17 having knob 17 is handily located for controlling motor 23, the power for operation being-supplied through a plug connection 40 mounted on the back side of box-16 instead of through the plug connector 38 on .the air pump 20. A circuit diagram of the table wiring is shown in Fig. 4 from which it is seen that switch 17 has seven points and is similar in every respect to switch 24 described above- The; switch 17 and the connector 40 have conductor wires leading down therefrom through aconduit 4-1 passing under the shelf 15 and terminating in a series of spaced rigidly secured male plug members a, b, 0,

cl, 6', and f upstanding and extending through the shelf 15 as shown in Fig. 1. A corresponding set of female socket members a, Z), 0, (Z, c, and fare fixedly fastened to extend inwardly from the bottom side of the air pump 20 for co-operatingly engaging with the said male members, the female members being connected into the air pump wiring circuit as shmvn in Fig. 3.

This male and female conincting means forms a simple, easy and quick detachable mounting which intcrcoimects the table control switch 17 on mounting the air pump .20 in place on shelf 15.

There may also be provided a pair of spaced upstanding pins 15 secured on the shelf 15 and a corresponding spaced pair of holes 21 extending up from the bottom of the air pump 20 to facilitate guiding the latter in proper mounting position for aligning the said male and female connector members.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A surgical apparatus comprising a table, a motor driven air pump detachably supported by the table, and an electric wiring installation having portions thereof permanently mounted on the table and on the air pump, and means for disconnecting said portions simultaneously with the removal of the air pump from saidtable.

5. A surgical. apparatus comprising a table having a shelf, a motor driven air pump detachably supported. by the shelf, and an electric wiring installation having portions thereof permanently mounted on the ta b]c and on the air pump, and means for disconnecting said portions simultaneously with the ren'ioval of the air pump from said table, said means comprising male connector members rigidly secured in upstanding position on the shelili and corresponding ei'igageable female members fastened to the baseboard to extend therein from the bottom side thereof, and spaced pins for guiding said connector members to aligning position when mounting the air pump on the shelf.
